Mice were also treated with UV alone and with 2-EHMC alone. The accumulated UV exposure alone produced tumours in 40-100% of mice. There was a relatively good correlation between the PF and the sun protection factor (SPF) claimed for each sunscreen by the manufacturer. #The private collection of sandra orlow nude skinHowever, the PF values determined in mouse skin were generally higher than the SPF values measured in human skin. Further studies are needed to determine if sunscreen substantivity (resistance to removal by water) can be evaluated by this techniqueSkin barrier disruption by acetone: observations in a hairless mouse skin modelRissmann, R. Bouwstra, J.A.To disrupt the barrier function of the skin, different in vivo methods have been established, e.g., by acetone wiping or tape-stripping. In this study, the acetone-induced barrier disruption of hairless mice was investigated in order to establish a reliable model to study beneficial, long-termUltraviolet carcinogenesis in the hairless mouse skin. We suggest that the CR hairless rat mutation and fuzzy be renamed frizzy-Charles River (fr(CR)) and frizzy-Harlan (fr(H)), respectively, to reflect their likely orthology with the mouse fr mutation.Evaluation of seven sunscreens on hairless mouse skinThe ability of seven sunscreens to protect against ultraviolet (UV)-induced inhibition of epidermal DNA synthesis was evaluated in vivo using a hairless mouse model. There were statistically significant differences among sunscreens in their ability to prevent UV-B (290 to 320 nm) inhibition of DNA synthesis. The protective factor (PF) of a sunscreen was arbitrarily defined as the ratio of the dose required to inhibit DNA synthesis by 50% with and without a sunscreen. The following PF values were determined: Coppertone 4, 4.4 Sundown Extra Protection, 8.4 Supershade 15, 21.0 Eclipse 15, 22.2 Blockout 15, 22.4 and Bain de Soleil 15, 27.6. However, the designation " hairless" has been used as an extension of the hairless mouse (hr) nomenclature on the basis of the clinical absence of hairs in both phenotypes. We present a description of the histopathologic changes in heterozygous and homozygous CR hairless rat mutants during the first month of life. The postnatal homozygous rat skin was characterized by abnormal keratinization of the hair shaft and formation of a thick and dense layer of corneocytes in the lower portion of the epidermal stratum corneum. This layer prevented the improperly keratinized hair shaft from penetrating the skin surface. Starting from the latest stages of hair follicle (HF) development, obvious signs of HF degeneration were observed in homozygous skin. This process was extremely rapid, and by day 12, mainly atrophic HFs with abnormal or broken hairs were present in the skin.
